Abstract

Features of the present invention are connected with an optical recording medium which comprises a substrate, a heat-senstive color-developing layer containing a basic dye and an organic developer, and a light-absorbing layer containing a near infrared absorbent, the aforesaid layers being superposed upon the substrate, a reflectance at the dominant wave length of a laser beam on the surface of the recording medium being from 15 to 65%; a method for recording by irradiating the optical recording medium with a laser beam condensed by a condenser having a focal length of 0.5 mm or more and a numerical aperture (N.A) of 0.1 to 0.5;
and a device for use in the above-mentioned method.
